2 Functional Overview
This section provides an overview of the architectural structure and peripheral devices of the Medio
P213 TAGSYS RFID Tag Reader. It also provides a summary of the special functions used to drive
the reader board and describes the automatic features managed by the Central Processing Unit
(CPU).
2.1
Functional Block Diagram
The Medio P213 architectural structure is based on a CPU that drives all reader functions.
It manages communications between the host system (connected to the “Reader-to-Host
interface”) and one or more TAGSYS RFID Tags using an antenna (connected to the “Tag-toReader interface”).
It also drives 1 Universal Input and 1 Universal Outputs.
Figure 2 illustrates the general architecture of Medio P213 TAGSYS RFID Tag Reader.

2.2
Communication Protocols
2.2.1
Tag-to-Reader Interface
To read from TAGSYS RFID Tags, to write to their memory, or to activate their functions, a wide
command set is available. For a complete list of embedded commands and their description,
please refer to the Medio P213 Command Set document.
2.2.2
Reader-to-Host Interface
When the Medio P213 reader is connected to an antenna, it acts more as a protocol converter due
to the wide range of tasks it can perform. For more information about these tasks, refer to the
Medio P213 Command Set document.
Depending on the task requested by the user through the host interface, the reader retrieves
information from the TAGSYS RFID Tag or provides it with information using its own
communication protocol. The reader then converts the result of the operation into STX-E protocol
and returns the information to the host via the Reader-to-Host interface. For more information, refer
to the Medio P213 Command Set document.
The Reader-to-Host interface has two operating modes:
1. Normal Mode
The Reader-to-Host interface is the slave of the master host system. It waits for a valid
command from the host, performs the task and responds. This bi-directional
communication is achieved via the STX-E protocol. (For more information, please refer to
the Medio P213 Command Set document.)
2. Stand-alone Mode
The Reader-to-Host interface is independent from the host system. Stand-alone mode is
used by the Medio P213 reader to read tags and send their identification data to the host
system. This transmission takes place in ASCII format. While in this mode, the reader
cannot receive any commands.
For more information, please refer to Section 7, “Stand-alone Mode”.
2.3
Peripheral Devices
The I/O interface manages 1 input and 1 output that can drive or check external peripherals.
The input is compliant with open collector drivers, TTL/CMOS voltage levels and industrial levels
(up to 25V).
The output consists of a gate controlled MOSFET transistor driver that can drive up to 1.5A. It is
safe from current and thermal overloads. +5V current limited option is available to give TTL/CMOS
compliant levels.
The I/O pins are mainly used for static applications such as reading sensors or driving LEDs,
relays or buzzers. For more information, refer to Section 6.1 “Using the Universal Input pin” and
Section 6.2 “Using the Universal Output pin”.

4 Serial Communication Links
Medio P213 TAGSYS RFID Tag Readers are based on a Master-Slave communication system
where the host system acts as the master and the reader as the slave.
In Stand-alone mode, the reader is used as a master and the host system becomes the slave.
The Host-to-Reader interface accepts an RS-232, RS-422 or RS-485 (Full or Half Duplex)
communication links. The communication type is selected using the jumpers on the Serial
communication selector :

RS-422 / RS-485 Interface
The RS-422 interface is compatible with EIA/TIA-422 standards.
The RS-485 interface is compatible with EIA/TIA-485 standards.
The RS-485 permits a balanced transmission line to be shared in Party Line or Multi-drop
mode. As many as 32 receiver (readers or repeaters) pairs can share a Multi-drop
network. If more readers are needed in the network, balanced line repeaters can be used
(a repeater takes the place of a reader on the network).
4.3.1
Installing the RS-422 Interface
Figure 4 shows how to connect the RS-422 interface. The balanced line RX+ and RX- corresponds
to the reader receiver and must be connected to the transmitter of the host. The balanced line TX+
and TX- corresponds to the reader transceiver and must be connected to the receiver of the host.
A 120-Ohm resistor should be
added at the end of a transmission
line in compliance with RS-422
specifications. This resistor can be
connected by connecting a jumper
on
the
RS422
Terminaison
selector.
When set to communicate according to RS-422 specifications, the reader always holds its
transceiver active and never switches it into Tri-state mode. The Host-to-Reader Interface should
not be unplugged.

Installing the RS-485 Full Duplex Interface
The RS-485 Full Duplex Standard requires 2 pairs of balanced lines, one for transmitting and
another for receiving data.
When testing your network installation, make sure that all the connected readers are :
- correctly supplied
- correctly configured (Communication link selector and Terminaison resistor)
- correctly connected (cable connections)
If one reader is faulty on the network, all the network may be mute to any command sent over
the network.
Make sure that all the readers are preset with a different network address to avoid network
conflicts. By default, a Medio P213 is preset with address 0.

Figure 5 shows how to connect the RS-485 Full Duplex Interface in a Multi-drop network.
The balanced line TX+ and TX- corresponds to the reader transceiver and must be connected to
the receiver of the host (and other reader transceivers or repeater).
A 120-Ohm resistor should be added at the end of the two transmission lines in compliance with
RS-485 specifications. This resistor can be connected by connecting a jumper on the
RS422/RS485 Termination Selector on the end-line reader.
When set to communicate using the RS-485 interface, the reader always holds the transmission
lines before the start of any communication and returns to Tri-state mode at the end of
communication. The host system should do the same. The reader can be unplugged from the
balanced lines.
4.3.3
Installing the RS-485 Half Duplex Interface
RS-485 Half Duplex Standard requires only 1 pair of balanced lines, for both transmitting and
receiving data.

Medio P213 Reader User's Guide
When testing your network installation, make sure that all the connected readers are :
- correctly supplied
- correctly configured (Communication link selector and Termination resistor)
- correctly connected (cable connections)
If one reader is faulty on the network, all the network may be mute to any command sent over
the network.
Make sure that all the readers are preset with a different network address to avoid network
conflicts. By default, a Medio P213 is preset with address 0.
The balanced line TX+ and TX- corresponds to the reader driver and must be connected to the
driver of the host (and other reader drivers or repeater).
The RS-485 Half Duplex interface is configured by setting the reader in RS-485 Full Duplex
mode and connecting pins RX+ and RX- to pins TX+ and TX- pins respectively on each
reader of a network.

Grounding Arrangement
In order for the generator and the receiver to operate correctly, a signal return path must exist
between the reader grounds of the equipment at each end of the interconnection. The reader
reference may be established by a third conductor connecting the common leads of the devices, or
it may be provided by the connection from each equipment item to a ground reference. Where the
reader reference is provided by a third conductor, the connection between the reader common and
the third conductor must contain a certain amount of resistance (e.g. 100 ohms) to limit circulating
currents when other ground connections are provided for safety.

5 Connecting Peripheral Devices
5.1
Using the Universal Input pin
The reader input can be driven by a voltage source from 0V up to 24V referring to the input ground.
A relay (open chain transistor, switch…) can also be used to connect the input pin and its ground.
-
Low level input voltage is defined to be in the range of 0 to 1.5V
-
High level input voltage is defined to be in the range of 3 to 25V
5.2
Using the Universal Output pin
The output pin is an open drain power transistor that can drive a current up to 1.5A. When
activated, the power transistor connects the output pin and its ground.
The output transistor is protected against heating and current overload. If an overload happens, the
output stops driving current automatically. The output must be turned off to be re-activated.
You can use the Configurable
Supply Output pin of the IO
connector to deliver a supply to
an active system connected to
the output. You can set it to
deliver the supply used to
power the reader or a +5V
supply limited by a 470 Ohms
serial resistor by using the
Supply Output Pin Selector
with a jumper.

When the output is activated by the reader, a green led near the IO connector turns on.
Beware that the LED will stay on while the output is in thermal or current overload state.

Example 1 : Connecting a LED to the Output
The LED’s cathode is connected to the
Output pin and its anode to the Output Supply
Pin. Note that the Output supply jumper
selector is configured to deliver 5V to supply
the LED. The internal serial resistor limits the
current delivered to the LED.
Example 2 : Connecting a Lamp (5W under 24 V) to the Output using the reader supply
The common wire (-) of the lamp is
connected to the Output pin (J3-2) and its
supply to the Output Supply Pin (J3-1). Note
that the Output supply selector is configured
to deliver the Power of the reader to the lamp.
The lamp needs a 24V power supply, so the
reader is supplied with 24V. The consumption
of the lamp is less than 1 Ampere, so it can
be connected directly to the reader output.

6 Stand-alone Mode
Stand-alone Mode is designed to use the reader without using any command set. While in this
mode, the reader is limited to tag reading.
The reader sends the tag ID to the Host System using ASCII protocol via the Reader-to-Host
interface.
ASCII protocol is used in order to provide hexadecimal data that can be read by a variety of
terminal programs (e.g. Microsoft® HyperTerminal).

Repetition Option
The reader constantly attempts to read any chips present in the field. When a chip ID is detected,
the reader can send the information to the host in one of 2 modes:
1. In “Repeated Read” mode, the reader returns a chip’s ID to the host with each successful
read operation.
2. In “Read Once” mode, the reader only returns the ID of a chip if the previous read
corresponds to a different chip, or if all reading attempts have failed 4 times (this feature
makes it possible to detect a chip’s potential exit out of the field).

Trigger Input
When the trigger capability is enabled, a trigger state is used to start and stop the RF scanning.
The trigger is connected to the input of the reader.
Depending on the reply settings of the trigger, the ASCII message can be sent during the trigger
activity (Repeated Read mode and Read Once mode are available) or at the end of the trigger. In
this last case, a message is always sent to the host system:
♣ if a tag has been read, the message contains its ID,
♣ if a tag has not been read, the message contains a No Message string (that can be defined)
as shown in Table 11.
